Electron Gun - Effects of a Magnetic Field Purpose: The objective of this experiment is to study the motion of an electron in a magnetic field and to establish (show/verify) a relationship between the magnetic strength and the distance the electrons are deflected. Theory and Procedure: The electron gun is an instrument that consists of an electron source (which emits electrons and focus the stream into a beam)‚ a magnetic coil (which uses a voltage to create a magnetic field that deflects the beam

The magnetic separator is one of commonly used preparation equipments in magnetic separation factory. It has dry and wet two types. According to types of magnets‚ it can be divided into permanent magnet type and electromagnet type. It is also can be divided into strong magnet type‚ middle magnet type and weak magnet type according to the magnetic field strength. Different magnetic separators have different characteristics and performance. The common things have magnetite iron ore (belong to strong

charge‚ i.e. charge to mass ratio ‚ of an electron using m Thomson’s bar magnet method. Basic methodology: Electrons in a CRT are deflected in the vertical direction by applying a potential between the vertical deflection plates of the CRT. A magnetic field perpendicular to the deflecting electric field is produced using a pair of bar magnets. The position of the magnets is adjusted so as to cancel the deflection of the electrons. The knowledge of the deflecting potential and the magnet field

Effect of The Earth’s magnetic field By X 9h Earth’s Magnetic Field Introduction Our Earth is a huge bar magnet tilted 11 degrees from the spin axis of the Earth‚ with geographic north pole being earth’s magnetic south pole and vice versa. Similar to how a magnet has a magnetic field surrounding it‚ our Earth also has its own magnetic field. The earth’s magnetic field is formed in the earth’s core due to a process known as the dynamo effect. According to dynamo effect

The Magnetic Separator can separate raw materials with different magnetic rigidities. The machine works under the magnetic force and machine force.Magnetic Separators are designed to recover ferromagnetic materials. The separators are available in designs and sizes to provide solutions for all applications. The heart of each separator is the magnetic system with its unique design‚ which has a proven record of high efficiency. Slurry magnetic separator (magnetic the separator) to mine box into the

You see it everywhere in magazine articles and advertisements‚ but what exactly is a core competence? At its simplest‚ a core competence is a unique capability that affords some type of competitive advantage. It corresponds to a business process‚ and involves underlying skills‚ functions‚ systems and knowledge. To determine if something is of core competence‚ one must ask‚ "Does this ’thing’ give the company a unique advantage over its competitors and help make the company profitable"? Capabilities

Purpose: The purpose of these experiments[1] was to measure the exciting current and determine the core losses in a transformer using the open circuit test (experiment # 2) and to determine the equivalent circuit of a transformer by using the short circuit method (experiment # 3). Introduction: In order to determine the equivalent circuit parameters of a transformer two simple tests are used‚ namely the open-circuit test (experiment #2) and the short-circuit test (experiment #3). By performing
